Answer:
15
Step-by-step explanation:
To evaluate f(- 1) substitute x = - 1 into f(x), that is
f(- 1) = 5(2 - (- 1)) = 5(2 + 1) = 5 × 3 = 15
Answer:
Suppose the closest point is at p=(x0,y0), and set q=(−2,−3). Then the tangent to the parabola at p is perpendicular to ℓ, the line through p,q. and we end up numerically computing the roots from here.
Answer:
480ft squared
Step-by-step explanation:
length= 40*0.30= 12
area= length×width
area=40×12
40×12= 480
What’s not the right answer?
We know the opposite and adjacent sides of angle B, so we can use the inverse tangent to solve for its value.
tan(B)^-1 = 3/4
B = 64.4 degrees
